Hi Glenn, Did you install the rollup hotfix? That should take care of things.

I have a name server (IIS) on an internal box that answers to 192.168.254.30 & 31 I am publishing this server on ISA for external ip addresses xx.xx.xx.226 & .227. Every day or two, sometimes two weeks, one of the publishing rules fails. There are no errors, it just quits forwarding the request. It seems like it always happens after an attack on port 1434. From our logs: 12/10/2003, 1:28:59, 66.77.132.210, xx.xx.xx.253, Udp, 1034, 1434, -, BLOCKED, xx.xx.xx.xx, -, - 12/10/2003, 1:30:30, 211.154.52.146, xx.xx.xx.228, Udp, 4529, 53, -, BLOCKED, xx.xx.xx.xx, -, - Any ideas?
